Function diem_sdk::transaction_builder::stdlib::encode_create_validator_account_script_function

pub fn encode_create_validator_account_script_function(
    sliding_nonce: u64,
    new_account_address: AccountAddress,
    auth_key_prefix: Vec<u8, Global>,
    human_name: Vec<u8, Global>
) -> TransactionPayload

Summary

Creates a Validator account. This transaction can only be sent by the Diem Root account.

Technical Description

Creates an account with a Validator role at new_account_address, with authentication key auth_key_prefix | new_account_address. It publishes a ValidatorConfig::ValidatorConfig resource with empty config, and operator_account fields. The human_name field of the ValidatorConfig::ValidatorConfig is set to the passed in human_name. This script does not add the validator to the validator set or the system, but only creates the account. Authentication keys, prefixes, and how to construct them from an ed25519 public key are described here.

Events

Successful execution will emit:

• A DiemAccount::CreateAccountEvent with the created field being new_account_address, and the rold_id field being Roles::VALIDATOR_ROLE_ID. This is emitted on the DiemAccount::AccountOperationsCapability creation_events handle.
